C# 将ColorItem添加到列表时发生灾难性故障

我正在尝试构建一个选择器，让用户从一些颜色中进行选择

我正在使用

RadListPicker

组件，代码如下：

<telerikInput:RadListPicker IsEnabled="True" Grid.Row="4" Header="Tile color: " InlineModeThreshold="3" x:Name="listPicker2" ItemsSource="{Binding Items, Source={StaticResource ColorItems}}" SelectedItem="{Binding TileColor, Mode=TwoWay}">
    <telerikInput:RadListPicker.ItemTemplate>
         <DataTemplate>
             <StackPanel Orientation="Horizontal">
                 <Rectangle Fill="{Binding ColorName}" Width="24" Height="24"/>
                 <TextBlock Text="{Binding ColorName}" Margin="12 -3 0 0"/>
             </StackPanel>
         </DataTemplate>
    </telerikInput:RadListPicker.ItemTemplate>
</telerikInput:RadListPicker>

而

ColorItem

是：

public class ColorItem
{
    public ColorItem(Color color, string name)
    {
        this.Color = color;
        this.ColorName = name;
    }

    public Color Color
    {
        get;
        set;
    }

    public string ColorName
    {
        get;
        set;
    }
}

如您所见，在

ColorItems.\u ColorItems

中，我有一些注释行。 没有这些线，一切都会顺利进行

（请注意，错误和消息是从意大利语翻译过来的，因此它们可能不像您预期的那样准确）

但当我只启用其中一个时，它会抛出一个异常，表示：

System.Windows.ni.dll中的首次异常“System.exception” 灾难性故障（HRESULT异常：0x8000FFFF （E_）

我不知道为什么它会抛出如此可怕的异常

这是完整的堆栈跟踪

有人知道发生了什么吗？

填充属性绑定到

ColorName

属性（可能不是Color）

最可能发生的情况是，矩形中填充了（由名称标识）而不是使用自定义定义的颜色

---

所以在大多数情况下，它是有效的，因为为自定义颜色指定的名称与预先定义的颜色匹配！但当它不匹配（注释的颜色）时，将找不到要显示的颜色，并可能发生灾难性故障或另一个异常；）

您正在将矩形的Fill属性绑定到ColorName（而不是Color？），可能该ColorName值不存在/在Windows Phone 8上不受支持？属性ColorItems在哪里？我的意思是来自注释行的ColorName值（如祖母绿、钢、灰褐色等）在Windows Phone 8上不存在/不受支持？异常听起来如此不真实，以至于当解决方案最简单时，我感到恐慌<代码>解决了所有问题，感谢您为我指明了正确的方向！如果不打算使用，为什么要创建颜色？
